Description
Technical field
The present invention relates to a kind of flax wet high grade yarn and strand production method, belong to the Textile Engineering technical field.
Background technology
Flax is a kind of natural fabric of function admirable, is called as the fiber queen.The linen fibre humidity absorption and release is fast, good permeability, is desirable wearing fabric in summer.At present, flax spinning mainly is the form that adopts wet spinning because the filament length of flax is shorter, therefore, can only adopt half deguming after thicker process of fiber (being fibre bundle) spin.Add the particularity of wet spinning process and equipment, make the wet spinning of flax be difficult to spin thinner yarn, can only make thick thick lining.At present, the spinning process of the long numb wet spinning of flax mainly is: scutched line (humidification health) → hackling → slivering → drafting → rove → boil and float → spun yarn wet spinning → drying → winder.And the cast tow wet spinning is to adopt the noil that produces in the hackling in the long fiber crops to spin to process, its spinning process each factory before rove is different, but the later operation of rove is in full accord with long bast fibre spinning, and just the space summary of longer bast fibre spinning of the drawing-off of tow system wet spinning frame is short.At present, the long numb wet-spun yarn of flax normally 16-24 public affairs is propped up, and the cast tow wet-spun yarn mainly is public of 10-20.In the linen yarn, more than 36 public is exactly high grade yarn.Especially 50 public reach above yarn, and to the requirement height of flax raw material, and production efficiency is low, and it is few that the historical facts or anecdotes border produces.
Simultaneously, except the fineness of yarn was thick, because poor to the control of fiber movement in the flax wet, the bar evenness of its yarn was also poor, the fiber crops grain is many, had seriously limited the application of linen yarn on knitting.
In the spinning of ramie and wool fibre, it is same because the fiber of ramie and hair is thicker, be difficult to spin high grade yarn, therefore, the technology that adopts the water soluble vinylon companion to spin occurred, promptly, polyvinyl alcohol fibre is mixed through shredding, combing with ramie or wool fibre, carry out grilling, rove and spun yarn again, spin the blended yarn of ramie/polyvinyl or hair/polyvinyl, with the polyvinyl dissolving, obtain the thinner high grade yarn of fineness again.Production method as ZL200810207888.0 (production method of ramie high grade folded yarn), CN200910045392.2(ramie high-count yarn spun and strand), CN 200910051980.7(matches the production method that network spins ramie high grade yarn and Gao Zhi strand for one kind) etc.But, because the ramie and the wool spinning of wet spinning of flax and dry method spinning have very big difference, in the wet spinning, flax will float to improve the spinnability of flax through over-cooking after making rove, and in spun yarn processing, rove also will just form linen wet-spun yarn at last earlier through entering the drawing-off zone of spun yarn behind the tank again.Therefore, water soluble vinylon can't just mix with linen fibre before spinning process, and this has limited the feasibility that flax and water soluble vinylon blending or companion are spun greatly.
Because the existence of the problems referred to above makes to be difficult to produce high, expensive goods in the existing flax wet, is unfavorable for the diversified development of flax product kind, has limited the promotion and application of flax product to a great extent, has restricted the development of flax industry.
